Electronic differential pressure switch with commutator and for several calibration values. |
| 摘要 |
<p>The instant invention concerns an electronic differential pressure switch with commutator and electric signal on several calibration values, including a luminous radiation receiver transmitter group, formed from at least one photo-detector with two opposing photo-emitters, the feed currents of which can be simultaneously varied in an inversely proportional manner, by means of suitable control and adjustment means. <IMAGE></p> |
